Enclosed CNC lathes can release droplets of neat oil or water-miscible coolant during turning, drilling, grooving, threading, and related machining cycles. An oil mist collector draws contaminated air from the enclosure and separates suspended liquid before it escapes through doors, loading openings, seals, or other gaps.
A suitable collector cannot be selected from the lathe brand or enclosure size alone. The machining process, coolant, operating cycle, observed mist load, inlet arrangement, available power, mounting position, and maintenance access should be reviewed together.
Why CNC-lathe mist loads vary
Spindle speed, coolant delivery, tooling, workpiece material, temperature, cycle time, and enclosure design all influence the mist generated by a lathe. Door-opening frequency also matters because the enclosure must clear enough airborne contamination before an operator opens it.
Two machines from the same manufacturer can therefore require different extraction arrangements. A compact lathe does not automatically need the smallest collector, and a larger enclosure does not automatically need the highest-airflow model.
Information needed for collector selection
Provide the following information before a model or installation is proposed:
- Machine manufacturer and model
- Enclosure dimensions and known openings
- Neat oil or water-miscible coolant
- Typical spindle speed and coolant delivery
- Main machining cycles and operating hours
- Visible mist, smoke, vapor, or particulate
- Door-opening and loading frequency
- Proposed inlet and duct route
- Available mounting structure and service space
- Available voltage and frequency
Photographs of the machine top, enclosure panels, door area, and available installation space are often more useful than a machine name alone.
Capture contaminated air at the enclosure
The inlet should draw mist from the enclosure without interfering with moving components, doors, tool access, chip removal, or machine maintenance. The connection should be sealed and mechanically secure.
A short, practical duct route can help reduce avoidable resistance. Restricted hose, sharp bends, poor sealing, or an unsuitable inlet location can reduce effective capture even when nominal collector airflow appears sufficient.
Replacement air must enter the enclosure somewhere. Door seals, cable openings, conveyors, bar-feed interfaces, and other gaps influence airflow through the machine. These conditions should be considered during commissioning.
Compare the TINME airflow range
TINME lists four centrifugal CNC oil mist collector sizes in the current 50 Hz product data:
| Model | Nominal airflow at 50 Hz | Motor power | Inlet diameter |
|---|---|---|---|
| TM-250A | 600 m3/h | 0.25 kW | 125 mm |
| TM-370A | 1,000 m3/h | 0.37 kW | 150 mm |
| TM-750A | 1,400 m3/h | 0.75 kW | 150 mm |
| TM-1100A | 2,000 m3/h | 1.1 kW | 150 mm |
These values help compare models but are not a universal sizing formula. Final selection depends on the actual enclosure, contaminant, inlet arrangement, process, and operating conditions. Exact 60 Hz airflow values require confirmation.
Choose a mounting arrangement
Where the machine structure and manufacturer requirements allow, a collector may be considered for machine-top installation. A floor stand or side/wall bracket may be more suitable when the machine roof cannot support the unit or when service access, vibration, drainage, or layout makes direct mounting impractical.
The final arrangement should allow safe access to:
- Collector covers and internal filters
- Optional HEPA post-filter
- Inlet and clamps
- Drainage path
- Electrical isolation
- Lathe doors, panels, and service areas
Support strength and installation safety require application-specific confirmation.
Centrifugal separation and filtration
TINME collectors use a rotating separation stage to coalesce suspended droplets. Separated liquid moves toward the drainage path, while the remaining airflow passes through a multilayer filter.
For confirmed applications involving micromist, smoke, or vapor, an optional HEPA post-filter may be reviewed. The supplied TINME specification states performance up to 99.97% at 0.3 micrometers with this option. It does not state an H13 classification, and the figure should not be presented as the performance of every standard configuration.
A and A+ monitoring versions
TINME A+ models add filter-condition monitoring to the corresponding A model. The listed airflow, motor, inlet, weight, dimensions, filtration structure, and installation options remain the same for each paired model.
Monitoring may help maintenance planning, especially where machines run extended shifts. It does not replace physical inspection, safe isolation, or an application-specific maintenance interval.
Plan drainage and maintenance
Separated liquid needs a clear drainage route without restrictions, backflow, or leakage. Whether the liquid can be returned to the machine depends on fluid compatibility, contamination, the coolant system, and site procedure.
Inspection frequency should reflect the coolant, mist load, particulate, operating cycle, inlet condition, drainage, and filter configuration. Avoid promising a universal replacement interval.
Review documented CNC-lathe installations
TINME currently shows installation examples involving a HAAS ST-20, MAZAK QTE-200MSYL, and MAZAK QTE-300L CNC lathe. These machine names describe installation context only and do not imply sponsorship, endorsement, authorization, or official partnership.
Request an application review
Send the machine model, enclosure dimensions, coolant, production cycle, observed mist condition, available power, and installation photographs to TINME. The review can then compare airflow, filtration, mounting, drainage, and maintenance requirements.

FAQ
Can I select a collector from the CNC-lathe model alone?
No. The machine model helps identify the layout, but enclosure size, coolant, process, mist load, inlet arrangement, operating cycle, and installation conditions also matter.
Does the smallest lathe always need the 600 m3/h model?
No. Machine size alone is not a sizing rule. Continuous production, neat oil, high spindle speed, frequent door opening, or a restrictive inlet route can change the required arrangement.
Can one collector serve two CNC lathes?
It may be technically possible in some engineered ducted systems, but the combined airflow, balancing, simultaneous operation, isolation, drainage, and maintenance effects must be assessed.
Does an oil mist collector also remove smoke?
The required configuration depends on the emission. Applications involving micromist or smoke may require optional post-filtration and specific review.
Can separated coolant be returned to the lathe?
The collector provides a drainage path, but return arrangements depend on fluid compatibility, contamination, the machine coolant system, and the site’s approved procedure.
